How to price occupied buy and holds for wholesale deal..?

[Brittnie Stewart]

I do tenant placement in Baltimore, Maryland. I'm still a bit of a novice when it comes to wholesaling, simply because I haven't had many deals to gain the experience. But I do have my own buyers list. So, one of my investors is pretty much asking me to sell 30 of his properties. All have recently had work done to them within the last 5-6 years maybe. 26 out of 30 of them are occupied. 20 of those 30 is federally funded (section 8) tenants. He has given me each rental amount, CAP rate, and what he wants for it.

Here is an example of one of the properties:

Occupied property with a section 8 tenant in it is getting $1,359 per month. CAP Rate is 25.80%. Asking for $49,000. The property was bought in 2010 for $48,500.

My questions are:

What will this CAP rate mean for the next buyer?

How can I calculate to make sure that what he is asking for isn't too much and to make sure that I can also add on my fee? 

In your opinion, how would you price this house to a new buyer including the wholesale fee? 

Are there any questions or important pieces to the puzzle that I am not considering? 

Thanks for any feed back and advice.
